Do you mean from the ones in the Steampunk Fairytale piece? If that's the case the Wolf in that one is one of a pack of about 15 Wolves and the dude in this pic is their leader, so his armour and stilts are more powerful and streamlined than the others, they work on the same principle but the are not as bulky.

Thanks for the comment, this guy is actually a different charater - I'm workin on a graphic novel for this story and this wolf is the real big bad wolf and the rest are his hench-men. His armour is a more light-weight, streamlined and efficient version that the other wolves are wearing.
